Definitions
- the present invention relates to a transparent cosmetic gel with a viscosity of at least 15,000 mPas, containing a) xanthan gum (INCI: xanthan gum) and / or iota-carrageenan (INCI: carrageenan) and b) carboxymethylcellulose (INCI: cellulose gum), wherein the preparation is free from polyacrylates and carbomers.
- Skin care products usually creams, ointments or lotions, are mostly used to moisturize and re-oil the skin. Often, active ingredients are added to them that regenerate the skin and, for example, prevent and reduce its premature aging (e.g. the appearance of fine lines and wrinkles).
- cosmetics In addition to cleaning and caring for the skin, cosmetics also have an aesthetic function. They should "improve” the external appearance of the user according to the respective cultural ideas. Cosmetics thus fulfill a psychological and social function, as they increase the (visual) attractiveness of the user. This area primarily includes “decorative" cosmetics, which change the appearance of the user with the help of dyes applied to the skin. But cleaning and care products also have a positive influence indirectly, since clean, healthy skin corresponds to people's ideal of beauty. l In recent times there has been an increased trend towards “natural” cosmetics, the ingredients of which no longer come from petroleum products or should be chemically synthesized. The search for alternative ingredients that meet these criteria poses particular challenges for product developers.
- a particular challenge is the development of transparent, aqueous gels, because these are usually thickened with polymers based on acrylate polymers. According to the state of the art, no other class of compounds can be used to thicken more transparently.
- the problem can also arise that the microbial stability of the products must be guaranteed so that the product does not germinate or decompose microbially.
- parabens and other synthetic, antimicrobial substances are usually used in aqueous gels, since "natural" preservation methods such as "acidification” (i.e. lowering the pH value) are not necessary when using acrylate polymers. If polyacrylates are "acidified” with the formation of polyacrylic acid, the gel network that increases the viscosity breaks down.
- the object is surprisingly achieved by containing a transparent cosmetic gel with a viscosity of at least 15,000 mPas a) xanthan gum (INCI: xanthan gum) and / or iota-carrageenan (INCI: carrageenan) and b) carboxymethyl cellulose (INCI: cellulose gum), the preparation being free from polyacrylates and carbomers.
- a transparent cosmetic gel with a viscosity of at least 15,000 mPas a) xanthan gum (INCI: xanthan gum) and / or iota-carrageenan (INCI: carrageenan) and b) carboxymethyl cellulose (INCI: cellulose gum), the preparation being free from polyacrylates and carbomers.
- the viscosity is measured according to the invention as follows:
- the measurement is carried out at 25 ° C. and a frequency of 10 _1 rad / s in a 150 ml beaded rim glass using Rheomat R 123 from proRheo.
- measuring body 1 up to 10 Pas
- measuring body 2 from 10 Pas
- All viscosity measurements are always carried out 24 hours after the gel has been manufactured.
- a preparation is considered a transparent cosmetic gel if it has a transmission of at least 90% at 420 nm, 650 nm and 900 nm.
- the transmission is measured according to the invention as follows:
- the samples are measured in 1 cm disposable cuvettes against water as a reference.
- the cuvettes are made of polystyrene with a wall thickness of 1.25 mm.
- the transparent gel according to the invention is advantageously characterized in that the preparation has a tan d of 0.8 to 1.1.
- the measurement is carried out with a plate-plate measuring system (ARES 5) with a diameter of 50 mm and a gap of 1 mm.
- the measurement is carried out at 25 ° C with Peltier temperature control, the angular frequency is varied from 0.1 rad / s to 100 rad / s and 5 measuring points are determined per decade. After filling the measuring system, a waiting time of 5 minutes is observed and then the sample is measured.
- the preparation contains xanthan gum (INCI: Xanthan gum) or iota-carrageenan in a concentration of 0.01 to 1% by weight, based on the total weight of the preparation.
- the preparation contains the preparation xanthan gum (INCI: Xanthan gum) and iota-carrageenan, then the mixture of the two substances is used in a concentration of 0.01 to 1% by weight, based on the total weight of the preparation.
- the preparation contains carboxymethyl cellulose (INCI: Cellulose gum) in a concentration of 0.1 to 4% by weight, based on the total weight of the preparation.
- sodium carboxymethyl cellulose with a molecular weight of greater than 400 kDa (determination by means of SEC, MALLS) is particularly preferred. It is very particularly preferred according to the invention if this has a degree of substitution greater than 0.6.
- the preparation has a pH of less than 5.5.
- the benzoic acid, levulinic acid or anisic acid in an amount (individual concentration) of 0.1 to 1% by weight, based on the total weight of the preparation.
- the preparation contains water in a concentration of 50 to 98% by weight, based on the total weight of the preparation.
- the embodiments of the present invention which are advantageous according to the invention are characterized in that the preparation contains glycerol in a concentration of 1 to 15% by weight, based on the total weight of the preparation.
- the preparation contains ethanol in a concentration of 0.5 to 10% by weight, based on the total weight of the preparation.
- the embodiments of the present invention that are advantageous according to the invention are characterized in that the preparation xanthan gum (INCI: xanthan gum) or iota-carrageenan (INCI: carrageenan) and carboxymethyl cellulose (INCI: cellulose gum), in a weight ratio of 1: 5 to 1 : 20 contains.
- the advantageous embodiments of the present invention according to the invention are also characterized in that the preparation has one or more compounds selected from the group of compounds alpha-lipoic acid, folic acid, phytoene, D-biotin, coenzyme Q10, alpha-glucosyl rutin, carnitine, carnosine, natural and / or synthetic isoflavonoids, flavonoids, creatine, creatinine, taurine, b-alanine, panthenol, magnolol, honokiol, tocopheryl acetate, dihydroxyacetone; Thiamidol; 8-hexadecene-1, 16-dicarboxylic acid, glycerylglycose, (2-hydroxyethyl) urea, vitamin E or its derivatives, hyaluronic acid and / or its salts and / or licochalcone A contains.
- the preparation according to the invention contains phenoxyethanol, ethylhexylglycerol and / or 4-hydroxyacetophenone.
- Embodiments of the present invention which are advantageous according to the invention are also characterized in that the preparation contains one or more alkanediols from the group of compounds 1, 2-pentanediol, 1,2-hexanediol, 1,2-octanediol, 1,2-decanediol, 2-methyl Contains 1,3-propanediol.
- the preparation contains suspended matter or gas bubbles.
- the embodiments of the transparent gel which are advantageous according to the invention are characterized in that the preparation is free from 3- (4-methylbenzylidene) camphor, 2-hydroxy-4-methoxybenzophenone (INCI: oxybenzone), 4-methoxycinnamic acid -2-ethylhexyl ester (INCI octyl methoxycinnamate), octocrylene, parabens (especially methyl, propyl and butyl paraben), methyl isothiazolinone, chloromethyl isothiazolinone and DMDM hydantoin, polyethylene glycol ethers or polyethylene glycol esters.
